  From the DEUNA print set ...
 The transceiver cable connects the following signals from the DEUNA to
 the AUI connector:
     1   Power
     4   Power return
     6   Receive+
     7   Receive-
     10  Transmit+
     11  Transmit-
     14  Collision+
     15  Collision-
     20  Fuse low 
This is great information.  Thanks!
Just checked the DELQA printset which gives the following for the
20-pin BERG:
1 Power
2 (key, pin blocked)
4 Power Return
6 Receive +
7 Receive -
10 Transmit +
11 Transmit -
12 Shield
14 Collision +
15 Collision -
18 Control out circuit A
19 Control out circuit B
20 Fuse OK
which seems to agree entirely with the DEUNA information you
have.  This is good news!
  In addition, the other pins on the DEUNA connector
are:
     2   Power (same as pin 1)
     3   Power return (same as pin 4)
     5   Ground
     8   Ground
     9   Ground
     12  Ground
     13  Ground
     16  Ground
     17  Open
     18  Open
     19  Open 
Okay, very nice to know this.
  I'll try to get a chance to scan the DEUNA print
set this week and send it
 over to bitsavers. 
That would be great!  I don't think there is any particular urgency,
now that I have the BERG pinouts, but I'm sure the community
at large (and me) would appreciate having that online somewhere
in the future.
Many thanks!
